The invention relates to comprehensive parameter test equipment for a rail vehicle bogie, in particular to a framework positioning device for a comprehensive parameter detection table of a rail vehicle bogie. The device comprises a longitudinal framework positioning support (a), a transverse left framework positioning support (b) and a transverse right framework positioning support (c), and the three framework positioning supports are all fixed on a T-shaped groove ground rail (3) constructed in a concrete foundation through T-shaped bolts (2), wherein the longitudinal framework positioning support (a) is positioned on the front side of a test bed, and the transverse left framework positioning support (b) and the transverse right framework positioning support (c) are positioned on left and right sides of the test bed respectively. The device can quickly and accurately position the rail vehicle bogie frameworks of various specifications to meet the requirement for main kinetic parameter detection of the rail vehicle bogie in multiple running states.
